Hi all.

Renault Megane. 07.

Heating not working on settings 1,2 and 4,

Works on 3. Hot and cold.

Any ideas? Thanks

Check the wiring to the resistor pack for switching voltages when toggling fan speed switch. Also check connector for signs of resistance (melted connector).

Had it happen on an old golf of mine. Relay was gone. Got one in a breakers yard for €20, fitted it myself in less than 15 mins.

It could be a thermal fuse on the resistor pack cost about 2 euro to fix.

Title clarified. Sounds like relay.

If the OP means the blower settings are gone, then it's a power resistor module that's failed.
The only fix is to replace the whole unit.
It's a known Renault fault.
